Ventricular Partitioning Device for Heart Failure Volume Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for heart failure, such as drug therapy and invasive surgical procedures, are inadequate in effectively reducing ventricular volume and improving cardiac function, particularly for patients who do not qualify for heart transplants or require alternative solutions.
Innovation Solution
Development of ventricular volume reduction devices that partition the heart into productive and non-productive regions, utilizing adjustable and expandable implants with membranes and struts to securely anchor within the ventricle, assisting in pumping action and reducing ventricular volume through adjustable partitioning and pumping assistance mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If invasive surgical procedures are used to treat heart failure, then ventricular volume reduction is achieved, but the procedure complexity and risk increase
Solution Approach 1:
The ventricle is divided into functional segments using a partitioning device with multiple struts and membranes that create distinct productive and non-productive regions, allowing targeted volume reduction without requiring complex invasive surgery
Solution Approach 2:
A partitioning device acts as an intermediary element inserted into the ventricle to mechanically divide the chamber and reduce volume, serving as a less invasive alternative to direct surgical resection
2Volume of moving object
If ventricular partitioning is performed, then ventricular volume is reduced, but the device structure becomes more complex
Solution Approach 1:
The partitioning device applies local structural elements (struts and membranes) at specific locations within the ventricle to achieve volume reduction, rather than requiring a complex overall device structure
Solution Approach 2:
The device incorporates adjustable and expandable elements that can adapt to the ventricular geometry, reducing the need for a fixed complex structure while maintaining effective partitioning

AI summary
Devices and systems including implants (which may be removable) and methods of using them for reducing ventricular volume. The implants described herein are cardiac implants that may be inserted into a patient's heart, particularly the left ventricle. The implant may support the heart wall, or may be secured to the heart wall. The implants are typically ventricular partitioning device for partitioning the ventricle into productive and non-productive regions in order to reduce the ventricular volume.
